Khc^null wing clones. Mitotic recombination was used to generate Khc²⁷/Khc²⁷ null imaginal cells in first instar larvae that were Khc²⁷/Khc⁺ (test class) or Khc²⁷/Khc⁺; P{mini-w⁺, Khc⁺}/+ (control class). (A) Anterior margin of a test class wing showing part of a clone derived from a null imaginal cell (yellow bristles). Some bristles were bent or kinked (arrowheads). (B) Part of a clone in a control class wing (yellow bristles). (C) Comparison of the size distributions of test class (Khc^null) and control class (Khc^null; P{mini-w⁺, Khc⁺}) wing clones. Sample sizes were 285 test clones (filled circles) and 274 control clones (open circles). Log linear analysis indicated that the two size distributions were indistinguishable.
